摘　　要：根据电泵井优化设计九步法,利用液面法计算当前流压,建立电泵井产能、气体体积、泵排量模型,开发ESPStar优化设计软件,完成电泵井优化设计计算.29井次现场实测与计算结果对比表明：下泵后流压下降的动液面平均相对误差为-7.4％ ～5.7％,单井平均泵挂深度下降228 m,电泵机组抽吸能力与油井供液能力匹配好,能够为油田节约能耗、成本并提高油井产量.Based on the Nine - step optimization design method for electric pump well, the current flowing pressure is calculated by liquid level inspection. The comprehensive model of the productivity, gas volume and the delivery of the electric pump well is established; the optimization design for the well is ultimately completed by the specific- ally developed ESP star software. It is illustrated by comparing 29 individual well testing results that, the average related error of the working fluid level gets -7.4% -5.7% while the flowing pressure decreases which causes by the pump laying down ; meanwhile the average setting depth of the pump decreases by 228 m. As a result, the unit pumping capacity and the well feeding rate match better, and can also save oilfield energy and cost and improve the output of oil wells.
